It's okay to add Dexcool, you just won't be getting the benefit of the five year longevity it offers. It is ethylene glycol based and phosphate free, so it is compatible. There are some green phosphate free antifreezes out there, but I would completely drain, flush, and fill with Dexcool to start with a known commodity. This means removing hoses at the radiator and flushing all old coolant out. 10% of the old stuff left behind will neutralize the longevity of the Dexcool. It's worth it!
